Abstract

PERCEPTOR PARA DETECTAR UN ESTADO DE AVERIA, TAL COMO UNA TEMPERATURA EXCESIVA, UNA FUGA DE FLUIDO U OTRA IRREGULARIDAD. CONSTA DE UN CONDUCTOR ELECTRICO (18), DE UN ELEMENTO DIELECTRICO (20) Y DE UN ELEMENTO FORMADO POR UN COMPUESTO POLIMERO SOLIDO CONDUCTOR (22) QUE COMPRENDE UN POLIMERO SOLIDO Y PARTICULAS ELECTRICAMENTE CONDUCTORAS DISPERSAS EN DICHO POLIMERO, EL CUAL AUMENTA SU RESISTIVIDAD CUANDO EL PERCEPTOR ESTA EXPUESTO EN ESTADO DE AVERIA. EL CONDUCTOR ELECTRICO (18) Y EL ELEMENTO CONDUCTOR (22) ESTAN SEPARADOS POR EL ELEMENTO DIELECTRICO (20), FORMANDO UN CONDENSADOR ELECTRICO
